Dena Battle, the onetime House staffer turned tax lobbyist, is taking on an entirely new role as co-founder and president of the fundraising-centric Kidney Cancer Research Alliance, or KCCure.

The dramatic career change — Battle quit Capitol Counsel in order to focus on the fledgling nonprofit — is the latest step in the life-changing journey she set upon in 2009 when her husband, GOP communications aide Chris Battle, was diagnosed with metastatic kidney cancer.

House Republicans have been talking for years about bringing top individual and corporate tax rates down to 25 percent, but the tax overhaul plan they released on Friday offers a different approach.

The corporate tax rate of 35 percent would drop to 20 percent and the top individual rate of 39.6 percent would go down to 33 percent under the GOP plan. And small businesses organized as pass-through entities like partnerships, LLCs and S-corporations would be taxed at a rate of 25 percent.
